Fees
If you are new: creating a name on the registry costs a fixed amount of ETH. That payment is a speed bump for throwaway names. It does not mean the name is trusted, reserved, or allowed to message anyone. This page is about that filter, and why the amount is an ETH integer, not a dollar price.
Creating an operator or bot on ClankerIdentity requires an exact ETH amount (operatorFee / botFee, in wei, the smallest unit of ether). That amount is fixed at deploy. There is no setFee.
What the fee is
Section titled “What the fee is”A sunk-cost filter. A new label cost something to create, so casual register → abuse → revoke → repeat is more expensive.
It is not:
- A protective measure against well-funded abuse
- Authorization, reserved names, or “this human is known”
- The right to message anyone
- A frozen dollar “trust value”
Who you accept is Policy. Whether traffic is delivered is Transport.
Fee vs gas
Section titled “Fee vs gas”The registry fee is only part of what leaves your wallet. The network also charges gas (postage) for the transaction. Both come from the same ETH balance. clanker fund and clanker doctor budget fee(s) plus a small gas cushion. Prerequisites.
Wei, not dollars
Section titled “Wei, not dollars”The contract stores an integer. $50 in the docs is only a dated illustration at deploy. ETH/USD moves in months. USD inflation moves in years. People will experience “it costs 0.05 ETH to take a name,” not “it costs $50 of trust.”
A later fee is a new registry pin, not a tune. Successors must not usurp prior names.
Networks
Section titled “Networks”| Network | Operator fee | Bot fee | Notes |
|---|---|---|---|
| Anvil / local | Tiny or zero | Tiny or zero | Prefunded accounts; no faucet |
| Base Sepolia | ~0.001 ETH | ~0.0001 ETH | Faucet ETH, not a real filter. Live values from the contract |
| Base mainnet (not deployed) | Pick wei once | Same | Dated USD illustration only at deploy. Not a dollar promise |
Faucet drip vs fee (Sepolia)
Section titled “Faucet drip vs fee (Sepolia)”The CDP faucet documents 0.0001 ETH per claim. That is less than the Sepolia operator fee. One claim cannot fund clanker operator mint. Use clanker fund (it estimates how many claims you need) or another Base Sepolia faucet. Details: Prerequisites.
